YL-ADL E--TIILTING DEVICE.

SPECIFICATION forming part of Letters Patent N0. 761,393, dated May 31, 1904*.

To all whom, it ntayconce'rn':

Be it known that'I, WILLIAM J. PATTERSON, a resident of Pittsburg, in the countyof Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Ladle-Tilting Devices; and I do hereby declare description thereof. 1 v

My invention relates to a ladle-tilting de-v vice, and more especially for use in connectionwith pig-metal-castin g apparatus in which the metal is discharged into a series ofmolds mounted on an endless chain, such as shown in Letters Patent of the. United States No. 583 124, granted to A. M. Acklin' the25thday of May, 1897. A i I The object ofmyinvention is to provide a simple form of apparatus adapted to be quickly connected-up to the operating-shaft of any ordinary tilting ladle to'drive. said shaft and adapted to be withdrawn when not in use, so

as not to interfere with the operations of the workmen about the plant.

To these ends my invention comprises, generally stated, a swinging frame having a power-driven shaft thereon and adapted to make connection with and operate the tilting mechanismof a tilting ladle. I

My invention. further comprises the novel features hereinafter set forth and claimed. I

.To enable those skilled in the art to make and use my invention,I will describe'the same more fully, referring to the accompanying I drawings, in which Figure 1 is a vertical elevation of my improved ladle-tilting device. Fig.2 is a like view at right angles thereto. Fig. 3 is a plan view. Fig.4 is an enlarged plan viewof the drivingahdreversing mechanism. Fig." 5: is

an enlarged sectionalview of the clutch mechanism. I

Like numerals indicate like parts in each of the figures.

The numeral 2 designates a building suitable fo'rthe purpose of containing the apparatus and into which the ladle-cars may be run for thepurpose of pouring. The tracks 3 are laid into the building, and on said tracks Application filed February 5 1903. 5 Serial No. 141,956. (No model.)

is the bearing-block 13, mounted in guides 14 tilting ladle5. Theladle 5 is supported ontrunnions in the" ordinary manner and is pro- ;vided with the worm-wheel 6 and worm-shaft .7, all of the ordinary construction. A swinging frame 8 is suspended from the shaft 9, said frame being preferablycomposcd of an glerbars 1Q, suitably connected and having the bearing-block 12 by means of which said frame is suspended from said shaft Qand is adapted to swing thereon. i At the lower end of the swinging frame '8' and adapted to slide therein. A shaft 16 is journaled in the bearing-block 13, said shaft having-the sprocket-wheel 15 and extending out beyond the frame 8. i The bearing-block 13 is provided with the adjusting-screw 17, whereby said bearing-block may be adjusted totake np anywear in the chain 18. 1A secondsprocket wheel 19 is mounted on the shaft X xiila iflfih f am *sand'gin n i h th sprocket-wheel 15 over which the chain 18 passes.

At the V v weights 20, which Iaid in the swingingof the .lframewhen it is desired to move. the lower end of said frame out'of the way.

Theshaft 21 may be driven" by a suitable motor 22, and on'said shaft are the pinions 22 23.] g The pinion 22 meshes with the large gear-wheel 24: on the shaft9. The pinio meshes with. the intermediate gear-W1: 2?

on shaft26, said gear 25 meshing with p small gear-wheel 2'? on shaft 9. By this-art rangement of gears provision is made for reversing the direction of rotation. of the shaft 9 and for increasing and decreasing the speed of same. f v Any-suitable clutch mechanism may be emupper the frame 8 the ployed for effecting thereversal of the shaft 9, that shown consisting of the upright lever 28, connected to the sliding sleeve 2 9,c0n-

nected by the toggles 30 to suitable..' clutches v 31 32. These clutches, as illustrated in Fig. 5,

are composedof the disks 33and 34:, the disk. A

34 being secured to the shaft 9 and said'disks being connected by the bolts 34. Interposed between the disks 33 and 34 is the disk 34", secured to the sleeve 27 on the gear-wheel 27, said gear-wheel being loosely mountedon said shaft. It has only been deemed necessary to illustrate in detail this clutch mechanism with reference to the gear-wheel 27, as the construction for the large gear-wheel 24: is the same. The lever 28 is attached to the endless operating-rope 35, which passes around the pulley 36, thence over pulley 37 to pulley 38, whence it passes down and around the pulley 39, near the floor of the building. This operating-rope 35 is provided with handbuttons 40 for convenience in operating.

The shaft 16 is provided with the universal couplings 41 42, the outer one-adapted to be connected up to the worm-shaft 7, whereby provision is made for connecting up the shaft 16 to the worm-shaft 7 in case said shafts are not in exact alinement. This shaft 16 is supported by brackets 16 on the swinging frame 8, the outer end of said shaft carrying the coupling 42 being supported by the bracket 16 on the ladle frame. A shaft 16", supported by the bracket 16 on the ladle-frame, acts to hold. the bevel-gear'7 into engagement with the bevel-gear 7 on the wormshaft 7.

The operation of my improved ladle-tilting device is as follows: The ladle-ear is run into the casting-house on the tracks 3, and when the ladle is brought into proper position for pouring the coupling 42 is connected up to worm-shaft 7. The operator then grasps the proper hand-button 4:0 and pulls the operating-rope 35. This operates the clutch 32 and causes the shaft-line to be driven by pinion 22, meshing with large gear-wheel 24. The shaft 9 is rotated in the proper direction, and through the sprockets 15 19 and chain 18 the shaft 16 is also rotated. Power is thus transmitted from the swinging frame to the worm-shaft7 to effect the tilting of the ladle. The shaft 7 continues to rotate in a steady positive manner, so as to pour the metal in an even well-controlled stream until all the metal has been poured. The operator then grasps the other hand-button and by pulling the operating-rope 35 the clutch 32 is disengaged and clutch 31 thrown into engagement. The shaft 9 is now driven by the pinion 23 and large gear 25 and pinion 27 in the opposite direction and at an increased rate of speed. This reverses the direction of rotation of worm-shaft 7 and the ladle is brought back to its normal position and that' at an increased rate of speed over that of the tilting operation. In this manner the righting of the ladle is accomplished in less time and the empty ladle withdrawn and a full one brought into position for pouring and a greater amount of metal handled in a given time.

The swinging frame may be readily swung to one side when notin use, as the weighted upper end makes it possible to swing the frame with little exertion and acts to retain it in the inclined position. When withdrawn, the swinging frame'in no wise interferes with the movement of the ladle-ears or the locomotive used for transferring said cars.
